Chamaecyparis plant named ‘SMNCLGTB’

ABSTRACT

A new and distinct  Chamaecyparis  cultivar named ‘SMNCLGTB’ is disclosed, characterized by colorful foliage, having green and gold coloration. Foliage is distinctively soft and not prickly. Plants are low maintenance with a narrow form. The new cultivar is a  Chamaecyparis , suitable for ornamental garden purposes.

Latin name of the genus and species: Chamaecyparis lawsoniana.

Variety denomination: ‘SMNCLGTB’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of chance discovery by the inventor, Timothy Wood. This new variety, hereinafter referred to as ‘SMNCLGTB’, was selected as a naturally occurring branch mutation from an unnamed, unpatented Chamaecyparis lawsoniana. The novel variety was discovered in a poly-greenhouse in Grand Haven, Mich. during 2006.

After identifying the new variety as a potentially interesting selection, first propagation of ‘SMNCLGTB’ occurred by softwood cuttings at a commercial nursery in Grand Haven, Mich. in 2010. The inventor continued controlled testing and propagation, assessing stability of the unique characteristics of this variety. Five generations have been reproduced and have shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘SMNCLGTB’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘SMNCLGTB’ These characteristics in combination distinguish ‘SMNCLGTB’ as a new and distinct Chamaecyparis cultivar:

-   -   1. Very colorful foliage with green and gold.     -   2. Soft texture.     -   3. Narrow plant form.     -   4. Low maintenance.

PARENT COMPARISON

‘SMNCLGTB’ is similar in most horticultural characteristics to the parent, however, plants of ‘SMNCLGTB’ differ in the following:

-   -   1. New cultivar has a softer texture; parent foliage is more         prickly.     -   2. The new cultivar has foliage with gold tips, the parent         variety does not have this distinctive coloration.

COMMERCIAL COMPARISON

‘SMNCLGTB’ can be compared to the commercial variety Chamaecyparis lawsoniana ‘MINLEM’, U.S. Plant Pat. No. 22,359. The varieties are similar in most horticultural characteristics, however, plants of ‘SMNCLGTB’ differ in the following ways:

-   -   3. New cultivar has a softer texture; comparator foliage is more         prickly.     -   4. New cultivar plant shape is more narrow than plants of this         comparator.     -   5. New cultivar's gold tips are more distinct; comparator has         less distinct color change within leaves.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color typical foliage of ‘SMNCLGTB’ on a mature plant of approximately 5 years old, grown outdoors in Grand Haven, Mich.

FIG. 2 illustrates a plant of the new variety at approximately 1.5 years old in a 3 gallon container.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
